PH40F Benchtop pH Meter: ISO 10523, SM 4500-H⁺

Metalsin‘s PH40F benchtop pH meter is a high-performance analytical instrument engineered for laboratories that require the highest level of regulatory adherence and diagnostic precision. Specifically designed for potable water, raw water, wastewater, and reclaimed water systems, the PH40F ensures that your facility remains compliant with the most stringent global environmental and safety standards.

Global Standards Compliance: 10523 & SM 4500-H⁺

PH40F Benchtop pH Meter is designed for precise and dependable pH measurement using the glass-electrode method. The instrument complies with ISO 10523 (Water Quality — Determination of pH) and (Standard Methods) SM 4500-H⁺, the internationally recognized reference standards for laboratory pH analysis of water and wastewater. By meeting the calibration, measurement, and performance requirements defined in these standards, the PH40F ensures accurate, reproducible results suitable for regulatory testing, environmental monitoring, and routine laboratory applications.

Advanced Electrode Diagnosis (Slope & Offset Display)

The PH40F benchtop pH meter: ISO 10523 & SM 4500-H⁺ compliant.

The PH40F features an Automatic Electrode Diagnosis system that displays the pH slope and offset values after every calibration. Accuracy is only as good as the electrode’s health. By monitoring the slope (efficiency) and offset (zero-point shift), technicians can predict when an electrode is nearing the end of its life or requires cleaning. This predictive maintenance prevents inaccurate readings before they occur, ensuring absolute confidence in every data point recorded for your water systems.

A Comprehensive Analytical Platform

Beyond its regulatory strengths, the PH40F is built with a massive 7.0-inch high-resolution LCD display for superior visibility of complex data. It features a versatile multi-reading system allowing for auto-read, timed-read, and continuous-read modes, alongside an Auto-hold function for stable endpoint detection. Connectivity is seamless via USB and RS-232 ports, supporting GLP-compliant data storage for up to 500 sets. The device offers high-level calibration flexibility (1-5 points) with automatic recognition for NIST, DIN, GB, USA, MERCK, and GOST buffer groups. Housed in an IP54 waterproof casing and equipped with both Automatic and Manual Temperature Compensation, the PH40F is as rugged as it is precise, ensuring long-term reliability in demanding laboratory environments.

Technical Parameters & Operation Manual

The PH40F benchtop pH meter is powered by an EU power adapter (input: AC 230V/50Hz; output: DC 20V/1000 mA), with configurable power adapter options available for different regions. It features a compact desktop design with dimensions of 242 × 195 × 68 mm and a lightweight net weight of 900 g (1.98 lb), making it easy to install and operate in laboratory environments. For transportation and storage, the packaging measures 370 × 305 × 330 mm, with a gross weight of 3 kg, ensuring safe and convenient handling.
